Change the maximum length of name of calculation result to longer value for CGNS library

[kskinoue0612]

Currently, the maximum length of name of calculation result is 32. But the CGNS documentation says
that 32 is the default value. Maybe we can change the max length to larger value.

There is a possibility that if we change the value of CGIO_MAX_NAME_LENGTH and recompile, we can
use longer value.

If it become apparent that it works, change the max length to a larger value, because solver developers wants to use longer names sometimes.
